How does an occupancy sensor work?
“An occupancy sensor turns the lights ON automatically when it detects motion within the viewing range. Also, turns the lights or motors OFF after a certain period when the room is empty and motion is no longer detected.
How do you detect occupancy in a building?
Other methods include microwave sensors, which emit low-power microwaves and detect changes in occupancy, and camera-based sensors, which take multiple images of the coverage area per second. Researchers are now exploring even more ways to detect occupants, such as light-differential sensing.
Are occupancy sensors required by IECC?
IECC 2018 requires that occupancy sensors be used in warehouses in open areas and aisles. These sensors must automatically reduce lighting power by at least 50% when areas are unoccupied. Each aisle must be separately controlled. Sensors controlling aisle lighting must not control lighting outside the aisle.
How does a vacancy sensor work on a car?
Manual-ON sensors (also called vacancy sensors) require the occupant to turn the lights ON using a manual switch, which may be integral to the sensor (shown here is an example). Partial-ON sensors activate the lights to a designated level such as 50%, and the occupant then uses a switch to bring the lights to full output.

Typically an occupancy sensor stays on for 30 to 20 minutes. However, there are other sensors that stay on only for 20 to 30 seconds. Occupancy-based lighting control strategies are a great way to save energy. They work by detecting when a person enters the room and turning off the lights when they leave.

What is occupancy sensor?
PIR occupancy sensors sense the difference in heat between moving people and their background. They can be installed on ceilings or walls, including as a wall switch replacement, and used in both indoor and outdoor applications. They are well suited to:
Why is it important to place occupancy sensors?
Improper mounting location is a leading cause of application problems with occupancy sensors, making sensor location a critical design decision. Sensors should be located so that they have the least possibility of nuisance switching and activate the lights as soon as a person enters the space. This typically involves sensor placement above or close to the main areas of activity in the space.
How do sound sensors work?
US sensors emit high-frequency sound waves into the space and detect occupancy from changes in the frequency of returning reflections, or they may set up a standing wave and measure both frequency shift and amplitude. They can be installed on ceilings or walls, including as a wall switch replacement, typically in indoor applications. Although they are an active technology (emit energy into the space), properly designed devices will not interfere with local devices such as hearing aids. They are well suited to applications requiring greater sensitivity and reliability, open indoor spaces, and spaces with obstacles. Suitable applications include open offices, private offices, bathrooms, classrooms and conference rooms.
How does occupancy sensor save energy?
Occupancy and vacancy sensors are devices that detect when a space is unoccupied and accordingly automatically turn OFF (or dim) the lights, thereby saving energy. The device may also turn the lights ON automatically upon detecting the presence of people, providing convenience and a potential security aid. According to the Lawrence Berkeley National Laboratory, occupancy-based strategies can produce average lighting energy savings of 24%.
How sensitive is a PIR sensor?
Most PIR sensors are sensitive to full body movement up to about 40 ft. but are sensitive to hand movement, which is more discrete, up to about 15 ft.
How much energy savings can occupancy sensors produce?
According to the Lawrence Berkeley National Laboratory, occupancy-based strategies can produce average lighting energy savings of 24%. Due to their relative simplicity and high energy-savings potential, coupled with energy code mandates, these sensors are a staple in new construction.
Where should PIR sensors be located?
PIR sensors should be located so that they have an unobstructed view of the primary task area. (While line-of-sight sensing can be limiting, it also enables the field of view to be limited at the factory by design or in the field through adjustment.) If full- or partial-ON, they should turn the lights ON immediately when an occupant enters the room.
Can I put a motion sensor on a 3-way switch?
When using in a 3-way application use one sensor and one standard 3-way switch. Cannot be used with another sensor, or in a 4-way application. WARNINGS AND CAUTIONS: If you are not sure about any part of these instructions, consult an electrician.
